Specification of Letters Patent. Patented NOV. 2?, 11911? Application filed January 29, 1917. Serial No. 1425,32 1.

To all whom it may concern:

Be it known that I, EARLE W. GoonNow, a citizen of the United States, residing at Lansing, county of Ingham, State of Michigan, have invented certain new and useful Improvements in Cooling Devices for Internal-Combustion Engines, of which the following is a' specification...

I This invention relates to improvements in cooling devices for internal combustion engines.

Considerable difliculty has been experienced in the cooling of internal combustion engines employed on agricultural machines such as grain harvesters, owing to the diihculty in properly installing the water cooled engines and the weight thereof and various other objections incident thereto and owing to the clogging and consequent inefiiciency of air cooled engines heretofore em- 7 ployed in that relation.

The main object of this invention is to provide in an internal combustion engine an improved cooling means which is efiicient and not likely to become clogged in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanyin drawing, forming a part of this specification, in which:

Figure I is a front elevation of an engine embodying the features of my invention, the base being indicated by dotted lines and certain other parts being shown conventionally.

Fig. II is a right hand elevation.

Fig. III is a detail view, partially in vertical section, on a line corresponding to line 3--3 of Fig. II.

Fig. IV isv a detail vertical section on a line corresponding to the broken line 4 -4: of Fig. I.

Fig. V is an enlarged detail section on a line corresponding to line 55 of Fig. II, showing the arrangement of the starting crank or hand piece.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the cylinder 1 is provided with circumferential heat radiatin flanges 2 connected by spaced connecting are or rods 3. These flanges are common to the valve chamber 4, which is formed integrally with the cylinder,-see Fig. III. The cylinder 1 is mounted upon the top section 5 of the crank case, which is hinged to the bottom section 6 at 7,see the dotted lines in Fig. IV, so that when the bolts 8 are removed the top section of the crank case and the parts mounted thereon may be tilted to facilitate the removal of the crank shaft 9, adjustment of the bearings, etc.

The bearings 10 are formed in sections, the sections being mounted on the top and bottom sections of the crank case. This arrangement of the crank case is substantially that shown in the Way Patent No. 870,001,

Nov. 5, 1907. The fly-wheel 11 is provided with a web 12 having an inwardly projecting annular flange 13 on its inner side.

The valve actuating mechanism, desig nated generally by the numeral 14, is disposed between the fly-wheel and the crank case. The control mechanism, designated generally by the numeral 15 is also disposed between the fly-wheel and the crank case. This control mechanism comprises governor weights 16 mounted upon the hub 17 on the inner side of the fly-wheel. The valve actuating and controlling mechanisms are not described herein in detail, as such details form no part of my present invention.

The cylinder is provided with a casing 18 which is open on the side-opposite the fly-- wheel. On the flange 13 of the fiy-wheel ll mount a fan 19, the fan being arranged to embrace the governor parts mounted upon and is mounted so that its outer edge 24 is' disposed between the fan and the fly-wheel, and embraces the flange 13 on the flywheel,see Fig. III, the fan of the flywheel constituting an outer wall for the fan casing. The upper section'of the fan casing is built as a part of the cylinder casing 18, that is, it is permanently joined thereto, the joints, however, not being shown. The fan casing is connected to the cylinder case by a throat having curved walls at 25 and 26 so that the air discharged from the fan is not obstructed in its passage to the cylinder and there are no places for material, such as chafl and the like to collect and clog the fan or the other parts.

The top 27 of the cylinder casing is hinged at 28 so that it may be swung back or opened to provide access to the interior of the casing.

With the parts thus arranged, I provide a structure which is very eflicient in cooling and also one which does not become clogged, even when embodied in engines employed upon harvesting machines and the like in which the air is usually charged with dust, chafl, small bits of straw and the like.

The parts are so arranged that the structure is very compact and the engine may be conveniently mounted for use upon ma chines, such as grain harvesters.

The starting crank orhandle 29 is pivoted at 30 within a recess 81 on the side of the fly-wheel, the handle being adapted to swing down into the recess, as shown in Figs. II and V, when not inuse.

I have illustrated and described my improvements in a very simple and practical embodiment in which I have developed the same for the market. I have not attempted to illustrate or describe certain modifications or adaptations in structural details which might be desirable for other adaptations, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
